With spiral staircases the rise to the next floor can be designed extremely space-saving. But with spiral staircases usually the striking effect and characteristic design is in the foreground, rather than the practical benefit.
This staircase model is made in accordance with an original sample from the penultimate turn of the century. The refined ornamentation combines with clear function - the old masters understood to unite ornament and constructive requirements: The ornamental lace pattern on the one hand save weight and on the other hand follow the lines of force in the construction.
Cast iron is an iron-carbon alloy with a high carbon content, which distinguishes this material from steel. The term "cast iron" is derived from the casting as a method of shaping from; cast iron parts are manufactured in a foundry. The material grey cast iron is cast iron alloy most commonly used throughout the world and contains carbon in the form of flake graphite. The material grey cast iron is easy to maintain and easy to cure. Grey cast iron is characterized by above-average wear resistance, excellent damping properties and a very good dimensional stability and impresses with both form and function.
The staircase components are produced in Germany by a foundry of a machine factory according to the traditional and technically advanced methods of the lost sand casting. The original model of the elements is molded in highly compacted sand. The molten iron is poured into the sand mold at 1500 ° C. After curing of the liquid iron, the sand mold is destroyed and the casting emerged. Thus, the sand mold is lost and must be re-established for each cast. After shelling out the casting, the element is cleaned by sandblasting and carefully retouched by hand.
Due to the the casting process the workpieces show a characteristic fine sparkling surface, which is retained even after the subsequent coating. As default colour a grey paint with metallic effect is used because it corresponds to the natural appearance of the material. p>
We offer other color finishes in RAL colors, as well as an additional galvanizing, on request.
The four basic elements of the stairs constitute a complete step-set. In conjunction with a spindle column the stairs can be assembled clockwise or counterclockwise in almost any height. P>

Despite standardized stairs building highly customized solutions can arise on the curtail step due to the structural conditions.
* Triple curtail step: To compensate for differences in height between a given storey height and possible step height (number of steps x step height) a different step height, double or triple curtail step, may be used at the beginning; this forms a kind of podium. Example: given storey height: 295 cm, possible number of steps: 15 x 19,00 cm = 285 cm => remaining difference: 10,00 cm. In this case, a double or triple curtail step would be provided with a height of 10.00 cm.
* Balancing rings: Reduced height differences can be compansated with intermediate rings (h = 2.5 mm) that are placed underneath the steps.
* Two or three times the outlet level: As a standardized outlet element we offer a twofold or threefold outlet level, which is used as the highest stage element. It forms a small platform area (48 ° or 72 °), and the storey can be accessed at the same level.
* On-site transitional design: A transitional construction of steel sheet to be drawn up on site combines the triple outlet level with the straight or round ceiling edge of the stairwell or gallery. Individual pedestal solutions without using the two- or threefold exit stage are also possible, however, these solutions have to be developed on site with your locksmith.

The staircase assembly is similar to a Meccano building set. For the assembly of the stairs as well as for the supply and customization of components on the construction site and the realisation of on site connection details, the cooperation with a local locksmith / metal worker is required.
The four basic elements of the stairs constitute a complete step-set. In conjunction with the spindle column that is supplied on site, the staircase is built with the running direction to the right (clockwise) or to the left (counterclockwise).
The first step of the mounting process is to place the spindle column supplied by your locksmith on the floor. The spindle column is a commercial steel pipe (Ø 88.9 mm) with welded base plate, which ranges over the entire height of the stairs, if necessary plus handrail height (cladding tubes). Treads and risers are pushed from above onto the spindle column, then the contact angle is inserted to stiffen, the threaded rod of the handrail rod is inserted and screwed from the bottom with the handrail rod cap. Step by step the staircase grows upward. Then, the stainless steel handrail is placed on the balusters and screwed in the threaded holes provided on the balusters. The handrail is delivered in pre-drilled subsegments (about 5 slopes) with plug-in connections. Alternatively, you can obtain a handrail according to your wishes from your locksmith. For fall protection of the stairwell or gallery additional balusters are available with the same design. The bar spacing of steps, stairwell- or gallery handrail can be made shorter using simple, round rods (Ø 6 mm) painted in the shade of the staircase (additional balusters).
The distance between the balusters is systemic and does not meet the building code in certain cases, where max. 12 cm clearance are required. To satisfy this requirementls on gallery handrails and staircase hole, additional balusters must be installed. The buyer is responsibility for compliance / non-compliance with building regulations.
